I like the visuals of the game! Gameplay was fun, reloading mechanics was well implemented to prevent spam-shooting. Repairing walls added a layer of hecticness to the game.
Feedback would mainly be on UI. Had trouble finding the checkbox for the "fullscreen" option (grey default checkbox on the background made it hard to see, plus it was oddly aligned). Might need a larger poll on this, but i felt that a tickingdown healthbar for walls would be more intuitive than the current tick-up damage indicator. A visual indicator of "in_reload" and "reload_complete" would be a nice QOL too (understand that there's already a bouncing effect at full magazine)
Solid entry overall!
